Margot Robbie sure knows how to make an entrance. When she attended the European premiere of I, Tonya [1], the Australian actress wore a long-sleeved custom gown by Louis Vuitton, which immediately reminded us of all the shimmery skating costumes she wore [2] in the film.

Needless to say, this dress automatically made it onto the list of her best red carpet looks [3]. Ahead, get a closer look at her stunning gown.
